It [was] like looking into the Grand Satelutes full of ice and coming back two years later to find it full of water," said Hubbard. In August last year, a square-mile sq km block of ice calved from the glacier.

Arctic sea ice has melted to a level not recorded since satellite observations started in — and almost certainly not experienced for at least 8, years, say polar scientists.

If current trends continue, a largely ice-free Arctic in the summer months is likely within 30 years —that is up to 40 years earlier than was anticipated in the last Intergovernmental Panel on Climate Change IPCC assessment report. The last time the Arctic was uncontestably free of summertime ice wasyears ago, at the height of the last major interglacial period, known as the Eemian. This year, both the North-west and North-east passages were mostly ice free, as they have been twice since The research will be published in a forthcoming issue of the Journal of Geophysical Research.

Photographs show that by July this year it had melted and disappeared. The previous one-day minimum was 4. Last month, the 74,tonne STI Heritage tanker passed through the North-east Passage with the assistance of ice breakers in just eight days on its way from Houston, Texas, to Thailand.

Daily satellite sea-ice maps released by Bremen university physicists show that with a week's more melt expected this year, the floating ice in the Arctic covered an area of 4.

Climate models show that the reduction is related to the man-made global warming, which, due to the albedo effect, is particularly pronounced in the Arctic," he said. Using records of air, wind and sea temperature, scientists from the Polar Science Centre of the University of WashingtonSeattle, announced last week that the Arctic sea-ice volume reached its lowest ever level in and was on course to set more records this year.

Arctic temperatures have risen more than twice as fast as the global average over the past half century. The north-east sea route, which links derretnedo Atlantic to the Pacific, is likely to become a commercial ship operator's favourite, saving thousands of miles and avoiding tolls on the Suez Canal tolls.

Arctic ice plays a critical role in regulating Earth's climate by staelites sunlight and keeping the polar region cool. Further evidence of dramatic change in the Arctic came last week from Alan Hubbard, a Welsh glaciologist at Aberystwyth University, who has been studying the Petermann glacier in northern Greenland for several years.
